Diet/Food & Feeding Habits

    It is not a safe tank mate for fellow tetra because it will eat small fish and it is not a safe tank mate for larger species because it is a notorious lepidophage. The tank can be well-planted. A tight fitting cover is required.


    Exodon paradoxus are attractive, easy to keep, not expensive, and long lived. They just donít get along with other fishes or each other.


    Use soft, peat-filtered water to initiate spawning. Eggs are scattered among plants, and the parents should be removed. The eggs hatch in 24-30 hours and the young can be fed micro-foods and Artemia nauplii. The young must be frequently sorted to prevent cannibalism.


    Breeding is very hard and not usually successful.


    This species is of typical elongated tetra appearance; it is light tan in appearance with two distinct black spots (one before the tail and another below the dorsal fin). The dorsal fin is bright red. The most obvious feature of the bucktooth are its large protruding teeth.


    A predatory species that should be kept singly or in schools of ten or more fish.
